Mplayer can't play TrueHD-audio

[russianneuromancer@…]

No any sound, when I try to play video with only TrueHD-tracks (without ac3 in TrueHD stream).
Two samples: ​http://sharebee.com/b2269f57

[compn]

did you try with newer mplayer?
rc2 came out before truehd existed...

rc2 is very old.

I try build ca17d1f-f29b3d9 from ​http://kovensky.project357.com/
I think this build enough fresh.

Despite an annoying number of messages without -channels 2 it does work for me.
And please use builds from SVN to report bugs here, we can't know what kind of code other MPlayer forks have exactly - better ask wherever you got the build from for help otherwise.
